RDBC = Ruby Database Connectivity.

This is English page. Japanese is here.
Sorry for Nakamura's POOOOOR English.
(The English translation of explanation below is by
Mr.SugHimsi. Thanx.)
This archive is an easy sample (I think so) for RDBC.

RDBC means Ruby Database Connectivity.
The target of RDBC is a unified(?) set of APIs
to access RDBMS like JDBC of Java.
The composition of RDBC is like that of JDBC.
Almost all the names of the classs and the methods
are mimiced. So(?) your knowledge of JDBC would
surely help you (and me ;-).
Currently, the bridges for Oracle and for Postgres
are prepared to connect RDBC with the actual
Database servers.
Those bridges merely call existent Ruby wrappers
written by the elder Ruby hackers. That is,
the oracle bridge is on the oracle module of Mr. Yoshidam,
and the postgres bridge on the postgres module of Mr. matz.

RDBC is not made only by me.
Many Hackers on some mailing list of ruby ( especially ruby-projects ml)
discussed for RDBC. I only made an example of implementation of RDBC.
May discussions be with RDBC.
